` INVENTOR Raaf/P7' c? .Sfr/vanaf ATTORN Y Patented Oct. 10, 1950 UNITEDSTATES PATENT OFFICE 15 Claims.

This invention relates to log loading equipment or the like, and more inparticular to a i log loading device which is mounted onto a truck orthe like and is adapted to lift logs from the ground onto a bed or deckand which utilizes power from a motor such as the internal combustionengine of the truck.

An object of this invention is to provide an improved log loader whichis of simplied and yet sturdy construction and which is efcient anddependable in operation. Another object is to provide an improved gearreduction and drive arrangement. Another object is to provide animproved winch or windlass. A further object is to provide apparatus ofthe above character which is adaptable for uses under a wide variety ofconditions. A still further object is to provide apparatus of the abovecharacter which is inexpensive to manufacture, maintain, and operate.These and other objects `will be in part obvious, and in part pointedout below.

The invention accordingly consists in the features of construction,combinations of elements,

and arrangements of parts as will be exemplified in the structure to behereinafter described and the scope of the application of which will beindicated in the following claims.

In the drawings:

Figure 1 is a perspective view of one embodi` Figure 4 is an end planview of the gear reduc` tion and clutch assembly of Figure 1;

Figure 5 is a fragmentary perspective view of the brake applyingstructure of Figure 5; and

Figure 6 is a sectional view on the line 6 5 of Figure 4:.

Referring particularly to Figure 1 of the drawings there is shown therear portion of a truck 2 having an open rack 3 with uprights'i adaptedto hold a load of logs. Mounted on the side of the truck is a loadingframe 6 which `has two loading arms 3 and a cross-frame structure ii).Each of the main loading arms has a right-angle extension i by means ofwhich the loading arm is hinged to the truck rack 3 and a main arm orlongitudinal portion 5 which has at its free end e. log-receivingportion S. This log-receiving portion E! is formed by `anupwardly-curved end bracket il and an angle-bracket i3 which. formsomewhat of a, channel within which the logs lie during the log liftingoperation. That is, the logs are rolled over the end extensions 9 of thetwo lifting arms against the angular brackets I3 and the two armscooperate to provide support for the logs. p

Each of the right-angle extensions 'I is formed by a channel I2 and anangle plate It welded thereto. A triangular reinforced plate I5 iswelded to channel l2 and the adjacent portion of arm `li and holds thesemembers rigidly together. Each-of the loading arms is hinged to theunderside of truck rack 3 by its hinge plate i4 which is positionedbetween a pair of mounting plates IB and is held by a removably pintlebolt IS extending through the plates. are welded to an angle bracket 2l!bolted to the truck rack and spaced from the edge of the truck rack asshown so that the loading frame is pivoted about an axis positioneddirectly beneath the truck rack and spaced a substantial distance fromthe edge of the rack. With this pivot axis thus positioned the loadingframe swings from the full line position of Figure 2 wherein the mainarms are substantially horizontal to the vertical position shown inbroken lines directly at the side of the truck rack. Y

The lifting frame is raised by means of a cable 22 which is connected tothe cable drum 23 of a winch or windlass 24 which is mounted slightly tothe right of the center of the truck rack. Cable 22 extends over a pairof pulleys 2t and 28 which are carried by an upright frame verticalangle bars 3i. Bar 32 carries a pair of downwardly projecting. pins 36which project' through holes in ear brackets 38 fixed to the truck rack.The upright frame is reinforced by a pair of plates 40 and the entireassembly is welded together so as to forma lightweight rigidconstruction. Angle bars 34 carry `U-shaped cable guards 42 adjacent thepulleys which prevent the cable from slipping of the pulleys. Frame 3i]is held in the upright position shown by a chain M ccnnectedat `one endthrough a clevis 455 to a bracket :i8 held by bolts 41 to the truckframe, and (see Figure 3) connected at the other end through a key holeand slot 49 in one of angle bars 34.

Cable 22 is attached to the loading frame ii `by a loop on the end ofthe cable which is received by a hook 59 (see also Figure 3) welded tothe center of the cross-frame structure i0. The cable extends from `thelifting frame over the top of pulley 26 (Figure-2) and thence downwardlyand Plates I6 beneath pulley 28 and to the left to drum 23 (see Figure6). The end of the cable is connected to the drum by a pair of U-clamps52 (only one of which is shown) the ends of which project through holesin an end ange on the drum and are held by nuts 54. Thus with thelifting frame in the full line position of Figure 2 the turning of drum23 winds the cable onto the drum and swings the lifting frame to theupright position shown in broken lines.

As indicated above, drum 23 is part of a winch or windlass 24 which isdriven from the truck motor and which includes a gear and brake assemblywhich is somewhat of the planetary gear type and which acts as a clutch.The arrangement is such that when the brake is released drum 23 remainsstationary, and when the brake is applied this drum is rotated. Drum 23includes a pair of cylindrical end anges 53 and 55, and a cylindricalmember 51 upon which the cable is Wound; the drum members are weldedtogether, and in turn welded to a shaft 56. Shaft 55 is supported at theright by a bracket 58 having a bearing 65', `and at the left by abracket 60 having a bearing 51. At the left end of shaft 56 and inalignment therewith is a shell 62 which is mounted at the right inbracket 50 through a mounting sleeve |56 welded to the shell and abearing 88. The bearing sleeve has a radial groove 69 into which acorrespondingly shaped ridge on bearing 68 fits so as to hold themembers in alignment, and sleeve and bearing |58 surround bearing 88 andshaft 56, thus to provide concentric support for shell 62 and the shaft.

Shell 62 is formed by two disc members or side Walls 6| and 53, and acylindrical member 59. Member 6| is welded at its periphery to member 59and member 53 is clamped to member 59 with an oil tight seal by aplurality of bolts 65. Shell 62 is supported at the left by a mountingsleeve 12 welded to the shell and journaled by a bearing 14 in a bracket54. Brackets 58, |50 and 64 are supported at the sides of the winch by apair of angle bars (see also Figure 4) 13 and 15. Journaled withinmounting sleeve 12 in alignment with shaft 56 is a drive shaft 18 whichhas a sleeve bearing 15. At the left-hand end of mounting sleeve 12there is an oil seal 11, and at the righthand end of mounting sleeve 66is a similar oil seal 19;

The right-hand end of drive shaft 18 projects into shell 52 and hasintegral with it a gear 8|), and the adjacent end of shaft 5S has keyedto it a gear SS. The adjacent ends of shafts 18 and 56 are held inspaced relationship by a washer 86 which is held in place by anextension S2 on the end of shaft 55, and there is a cylindrical recessin the adjacent end of shaft 18 which avoids direct contact between theends of the shafts. At the left of gear Bil is a washer 81, and at theright of gear 86 is a Washer 88', and these washers hold the gears fromcontact with the sides of the shell.

As shown in the upper portion of Figure 6, shell 62 also encloses a pairof gears 9!) and 92 which mesh respectively with gears 86 and 85. Gear99 has a cylindrical extension 9| upon which gear 92 is keyed and thetwo gears are mounted through a sleeve bearing 93 upon a shaft 95 withthere being washers 95 and 91 at the ends of the sleeve bearing to holdthe gears from the sides of the shell. The right-hand end of shaft 94projects into an opening 99 in member 53 of the shell and this providesa snug support for the shaft. A similar snug support is provided for theleft-hand end of shaft by an opening |00 in member 5| of the shell. Theleft-hand end of shaft 94 projects from the shell and has an in tegralflange 95 which is clamped to member 5| with an oil-tight seal by aplurality of stud bolts 98. At the right-hand end of shaft 94, opening99 is closed by a sealing disc |02 over which a cover plate |04; is heldby stud bolts IGS.

Shell 52 provides an oil-tight casing for the gears, and at the sametime forms with the gears a gear-reduction and clutch assembly. Thus, ifthe shell is hel-d stationary, the rotation of shaft 18 is transmittedthrough gears S0, S2, 95 and 36 to shaft 56 with there beingapproximately a sixto-one reduction in the speed of rotation. And, ifshell 52 is permitted to rotate and shaft 55 resists rotation, thenI therotation of shaft 18 causes gear 92 to tra'verse the periphery of gear86 and this causes shell 52 to rotate. As indicated above, a brake isprovided so that shell G2 may be stopped as desired; therefore, when thebrake is released the shell rotates freely with the result that drum 23does not turn, but when the brake is applied the rotation of the shellis stopped and then drum 23 is rotated by a direct gear drive.

The brake is formed by a brake band I9 having a brake lining ||2 whichengages the cylindrical braking surface of the shell which is the outersurface l of member 59. As shown best in Figure 5, brake band Il@ isfixed at one end to the supporting angle bar 15 and at the other end toa draw rod H5. Draw rod H5 is threaded at its right-hand end andprojects through a diametrical hole in a cylindrical operating pin |58.A pair of sleeves |25 and |22 are held into engage ment with theopposite sides of pin IIS by nuts |24 threaded onto rod M5. Pin H8 isrockably carried (see also Figure 5) by a pair of rectangular operatingblocks |25 which have a pin |28 l, projecting through holes in theirupper ends; the

blocks are clamped to the pin by bolts 21 and the pin is rockablymounted in a pair of xed brackets |30. Welded to one end of pin .|28 isa brakeapplying lever 32 which is normally biased down wardly (clockwisein Figure 4) by a coil spring lii one end of which engages the leverand. the other end of which engages angle bar 15. Thus a brake-applyingcrank is formed by blocks |25, pin |28, and lever |32, and spring |34normally acts through this crank to urge rod i i8 to the left (Figure 5)so as to release the brake from shell 62. The brake is applied bylifting arm |22 so as to swing the arm counter clockwise (Figure 5) thusto pull rod I5 to the right; this action tightens brake band Il upon theshell and tends to prevent rotation of the shell,

Lever |32 may be raised to apply the brake by pulling a cable |36 whichhas a loop at its end extending through a hole in lever |32 and whichextends upwardly and thence through a pulley |38 in a generallyhorizontal direction. As shown in Figure l, cable |35 extends forwardlybeneath the truck rack and is connected at the forward end of the rackto a lever |38. Lever |38 is welded to an operating bar |553 which ismounted on the truck rack by three brackets Mi and extends substantiallythe width of the truck with an operating handleV M2 at each of its ends.These handles normally project downwardly and when the operator wants tooperate the winch he swings one of the handles forwardly of the truckand this action is transmitted through lever |353A to cable |35 so that(see Figures 4 and 5) the brake-applying lever |32 is raised and thebrake is applied.

It has been indicated above that power is transmitted to drive shaft IBof the winch from the truck motor; for this purpose a winch clutch (notshown) is provided at the motor which provides continuous rotation ofshaft 18 when the winch clutch is engaged. Drive shaft IB (see Figure 1)is connected through a universal joint |43 to a shaft |45 which extendsforwardly of the truck and is supported by a bracket |4`| bolted to thetruck frame. Shaft |45 is connected at its forward end through auniversal joint |49 tol a shaft |5| which is in turn connected to thewinch clutch referred to above. During the log loading operation it isdesirable to provide for control of the truck motor by the operator.Accordingly, adjacent rod |43 is a similar rod |44 which is rookablymounted on the truck frame by a pair of brackets |44 and which has ateach end a control handle |48. Near the center of rod |44 is a lever |50to 'which a throttle control rod |53 is connected. Thus, an operator mayengage the winch clutch so as to start the rotation of shafts |5|, |45and '18; then he can control the raising of the loading frame 6 fromeither side of the truck and he has simultaneous control over the truckmotor.

In this embodiment of the invention the lifting action of the winch isstopped automatically at the time the loading frame 5 reaches its fullyelevated position. For this purpose the loading frame has abrake-releasing arm |52 (see also Figure 2) which is welded to one sideof the loading arm adjacent hinge plate I4. Brake releasing arm |52 isconnected through a cable |54 to cable |35:` (Figure l) by a cable clipat |53, and cable |54 extends through a ring loop bracket |53 so thatits end runs substantially parallel to cable 33. As the lifting framemoves toward the broken line position of Figure 2, arm |52 swings towardth-e side,` of the truck and this pulls cable |54. The length of cable|54 is such that it tightens up and exerts a brake-releasing pulloncable |36 at the time the loading frame approaches the broken lineposition of Figure 2. That is, as the lifting frame approaches thisbroken line position, arm' |52 pulls cable |54 and the force is exertedthrough cable |36 to lever |33 so as to swing this lever rearwardly ofthe truck and so as to move handles |42 back to their rest position.Therefore, the manual force exerted by the operator to apply the brakeand operate the winch is overcome so that the brake is released and thewinch no `longer rotates drum 23; thus, the drum is free to rotateby apull on cable 22. By this time the log or logs on the loading frame havebeen thrown or dropped into the truck rack, and the weight and mountingof the loading frame are such that cable 22 is unwound from drum 23 andthe loading frame starts to descend immediately to the full lineposition of Figure 2, In practice it has been found that an operator canload logs very rapidly because he can lift the loading frame at maximumspeed and can rely upon the brake-releasing mechanism to stop thelifting operation when the loading frame is fully elevated. Thereleasing of the brake in this manner may be regulated by adjusting thelength of cable |54, and in this way the varied demands of actual usemay be met. It has been found that a skilled operator can manipulatecontrol handles |42 and |48 in such a way as to load logs very rapidlyand he can even position the logs on the truck rack as he desires byvarying the speed of the motor dur ing the lifting movement.

The lifting frame may be mounted on either side of the truck and forthis purpose duplicate brackets I6, 38 and 48 are provided for theloading frame 6, the upright frame 3i) and chain 44, and abrake-releasing arm |52 is provided on each `of the loading arms 8. Thuswhen the operator wishes to load logs from the opposite side of thetruck he rst disconnects chain 44 from frame 30 and unhooks cables 22and |54 from the loading frame 6. The loading frame is then disconnectedby removing the two bolts i8 and is carried around to the other side ofthe truck., and the frame is held with the hinge plates I4 in theirrespective positions between the plates I6 while bolts I3 are inserted.Lifting frame 3Q is then lifted up so as to withdraw pins 35 from'brackets 38 and this frame is moved to the other side of the truck andpins 35 are inserted in the other pair of brackets 38; this may be donewithout removing cable 22 from pulleys 23 and 28. Chain 44 is thenconnected to the other bracket 43 by taking clevis 46 apart, and thechain is then attached at its free end to fram'e 3Q so as to hold theframe in upright position. Cable |54 is reattached to the arm |52 uponthe loading arm which is at that time positioned forwardly of the truckrack. Cable 22 leads olic from the bot* tom of drum 23 and with thearrangement of parts as shown the cable extends freely to pulley 28.Thus minimum effort is involved in adapting the apparatus from operationat one side of the rack to operation at the other side of the rack.

During movement of the truck from one posin tion to another, the liftingframe is held in the upright position shown in broken lines in Figure 2by a chain l5!) on the top of frame 30 which the operator connects (seeFigure 3) in a key hole opening |53 in a bracket |62 on the loadingframe. In the illustrative embodiment rack 3 is of the so-called opentype so that cable 22 can extend from drum 23 to pulley 23. Hoirrever,when the truck rack has a closed bed, pulley 'i8 is moved to a lowerposition indicated in broken lines and having its mount-ing pinpositioned in a hole |63. When pulley 28 is in this lower posi tioncable 22 extends beneath the truck rack (Figure 2) as indicated inbroken lines. Referring to Figure 6, drum `23 is provided with a cableguard |64 which holds the cable from jumping off the drum. The winch isenclosed in a sheet metal casing which has been generally omitted toshow the working parts.

As many possible embodiments may be made of the above invention and asmany changes` might be made in the embodiment above set forth, it is tobe understood thataall matter hereinbefore set forth, or shown in theaccompanying drawings, is to be interpreted as illustrative and not in alimiting sense.
